Definitions
- the present invention relates to a method and to a system intended for analysis and measurement of liquid or gaseous constituents contained in a drilling fluid.
- constituents designates here hydrocarbons, for example C1 to C8, including benzene, toluene, xylene, or gases such as H 2 S, CO 2 , O 2 , H 2 , N 2 .
- These constituents are due to drilling operations carried out through formation layers, operations that have the effect of breaking the rock, thereby releasing the gases or the fluids contained in the rock pores.
- Drilling is conventionally carried out with a circulation of a fluid referred to as drilling fluid whose function, among others, is to clean the drill bit and to drive the rock debris up to the ground surface.
- the constituents in question are therefore also carried along to the surface by means of this carrier. It is clear that, considering the flow rate of the drilling fluid compared to the rate of destruction of the rock, the volume amount of said constituents is always relatively low compared to the volume of mud.
- the object of the present invention is to implement the conditions required for: extraction of gaseous or liquid constituents contained in a drilling fluid, transportation of these constituents in gaseous form, and analyses and measurements of these constituents.
- the constituents In order to carry out correct analyses, allowing to better determine the nature and the composition of the formations crossed by a borehole, the constituents must not condense in the elements of the system and the time of transit of these constituents between the point of extraction and the point of measurement must be acceptable to allow the drilling operation to be monitored.
- the present invention thus relates to an extraction, analysis and measuring system intended for constituents carried along by a well fluid during drilling operations.
- the system comprises in combination:
- draw-off means for taking a determined volume of the fluid
- extraction means for extracting, in vapour form, the constituents contained in the volume of fluid, comprising a space placed under underpressure,
- vapour transport line a first end of which communicates with the space, the second end being connected to a vacuum pump
- sampling means placed in the vicinity of the second end, comprising a sampling loop that allows to sample a determined amount of the vapours circulating in said line,
- the space that contains the drilling fluid drawn off can be sealed against the outer environment.
- the space can comprise an inlet port for an auxiliary gas, air or nitrogen for example.
- the extraction means can comprise means for heating said volume of fluid sampled.
- the sampling loop can be mounted directly in parallel on the transport line.
- the drilling fluid draw-off means can comprise a suction pump and/or a discharge pump.
- the space can be at an absolute pressure ranging between 10 and 100 mb, and the suction of the vacuum pump can range between 1 and 10 mb.
- the invention also relates to an extraction, analysis and measuring method intended for constituents carried along by a well fluid during drilling operations, wherein the following stages are carried out:
- a volume of drilling fluid is drawn off and placed in a space belonging to extraction means intended for extraction of constituents in vapour form
- the underpressure and/or temperature conditions can be adjusted for extraction in vapour form as a function of the drilling parameters, for example the nature of the fluid, the flow rate, the ambient temperature, the time of transit in the line.
- a feed flow rate of the auxiliary gas fed into the space can be adjusted.
- An underpressure ranging between 10 and 100 mb in absolute pressure can be applied in the extraction space.
- FIG. 1 is an overall view of the system according to the invention.
- FIGS. 2 a and 2 b show the sampling device according to the prior art intended for analysis and measurement of the constituents in a chromatograph
- FIGS. 3 a and 3 b show the sampling device according to the invention intended for analysis and measurement of the constituents in a chromatograph under the present conditions.
- reference number 1 designates a flowline through which flows drilling fluid 2 returning from the well bottom by circulating in the annulus defmed by the drill string and the wellbore.
- This flowline 1 leads the drilling fluid from the wellhead to the surface installation for treatment and separation of the solids.
- Extraction means 3 intended for the constituents to be analyzed preferably comprise a pump 4 whose inlet 5 plunges into the drilling fluid and whose discharge end opens into a vessel 6 whose volume allows to hold as a buffer a determined volume of fluid for a given time, said time depending on this volume and on the flow rate of pump 4 .
- the volume of drilling fluid contained in vessel 6 is subjected to stirring in order to favour extraction through degassing and evaporation.
- This stirring operation can be mechanical, for example, by means of a rotating agitator 7 , or ultrasonic means.
- heating means 8 can comprise a heating rod 9 inside vessel 6 ,an electric power supply 10 and a control and regulation line 11 .
- Other means for heating the volume of fluid in the vessel can be used, for example from outside, or a double heating wall.
- the vessel also comprises a mud discharge line 12 intended for the fluid flow taken by the pump and returning to the flowline. It is possible to place a pump 13 on this discharge line so as to better control the rate of circulation of the drilling fluid retained in vessel 6 .
- a line 14 connects extraction means 3 to analysis and measuring means 20 .
- the length of this line can range between 50 and 200 m since measuring means 20 are placed in a cab (symbolized by frame 15 ) located at a sufficient distance from the wellhead to be in a secure zone.
- a vacuum pump 21 creates an underpressure that can reach several millibars (1 to 10 mb for example). Considering the pressure drops and the circulating gas flow, the underpressure at the inlet 22 of the line can range for example between 10 and 100 mb.
- Underpressure control means 60 can be placed in the vicinity of the end of line 14 , near extraction means 3 .
- These means can be a valve, a choke, or any other means allowing to vary the underpressure in the line and/or vessel 6 .
- the inside diameter of transport line 14 ranges between 5 and 15 mm, preferably about 10 mm.
- the material of the inner tube is selected to be impervious to hydrocarbons, such as for example fuel supply pipes. In order to prevent condensation of the gas conveyed, in certain extreme situations, it can be absolutely necessary to heat at least a portion of the wall, for example by means of a heating cord 23 .
- Vessel 6 comprises a gas inlet 24 for an inert gas or air, controlled by a valve 25 allowing to adjust the gas inflow rate. This valve can be controlled by means of a line 26 .
- sampling means 27 for the conveyed gas flow sample a certain amount of gas according to a rate depending notably on the measuring cycle.
- the sampler is controlled by line 28 .
- Sampling means 27 comprise: a loop referred to as ⁇ chromatograph>> loop in which a volume of gas is taken from line 14 , valves or distributors for carrying out this sampling operation, then for driving this volume of gas by pushing it with an inert fluid.
- FIGS. 3 a and 3 b diagrammatically shows injection line 29 for a carrier gas intended to displace the gas sample taken from line 14 by sampling means 27 , delivery line 30 intended to lead this volume of gas into analyzer 31 , for example a chromatography device.
- the measurements performed by means of device 31 are sent, by means of an electronic interface, to a central unit of a computer that processes these measurements in order to provide for example a record giving the nature and the amounts of the constituents carried along by the drilling fluid, according to the borehole depth.
- At least a zone of sampling means 27 and a portion of line 30 can be heated by heating means 33 in order to prevent condensation before or during measurement.
- Means 34 for eliminating or at least decreasing the steam content of the circulating gas flow can furthermore be placed on this line 30 .
- FIGS. 2 a and 2 b describe a conventional sampling valve 40 according to the prior art, which allows to better appreciate the considerable improvements provided by the present invention.
- line 41 communicates with an atmospheric degasser (not shown), the gases taken from the fluid being displaced in line 41 by means of an air circulation.
- Valve 42 once closed or partially closed, diverts the effluent so that it flows through valve 40 through channels D and C, then into sampling loop 43 prior to flowing back through the valve through channels F and E and to rejoining main line 41 .
- Channel A is connected to a carrier gas (air, helium, hydrogen or nitrogen) supply.
- Channel B is connected to the chromatographic analyzer.
- FIG. 2 b shows the circuit in analysis position.
- the position of the ball of valve 40 has been changed so that the carrier gas in A communicates with channel F to displace the effluent trapped in loop 43 towards the analyzer at B by passing through channel C.
- a bypass line of line 41 passes through channels D and E.
- the volume of gas sent into the analyzer is about some ten microlitres (10 ⁇ 6 l) at a pressure very close to the atmospheric pressure.
- FIG. 3 a shows a sampling valve 50 that can be similar to valve 40 of the prior art.
- Line 51 is placed under underpressure since it is connected to a vacuum pump.
- a sampling loop 53 can be connected to the line and to valve 50 as in the prior art, but lines 55 and 54 furthermore communicate directly with partial vacuum line 51 .
- Controlled valves 56 and 57 open or close these communications.
- the volume of sampling loop 53 is much greater than that of the prior art since the volume of the effluent is low at absolute pressure. In the embodiment described here, the volume of loop 53 is about 1000 ⁇ l.
- valve 50 is in sampling position, the effluent sucked by the vacuum pump flows through loop 53 by means of direct bypass lines 55 and 54 , valves 56 and 57 being open.
- Valve 52 can be more or less closed, according to the pressure drop required. If need be, the bypass line passing through C, D, F and E is always in operation. Thus, by selecting a sufficient inside diameter for lines 55 and 54 , the high pressure drops in the valve, due to the partial vacuum required for the present invention, are minimized.
- FIG. 3 b shows the circuits in analysis position. Valves 56 and 57 are closed, the sampling valve delivers the carrier gas from channel A to channel F so as to push the effluent contained in loop 53 towards the chromatographic analyzer at B.
- valve 52 is sufficiently open so that the underpressure is not limited by the pressure drops in circuits D and E.
- the effluent contained in the loop is partly compressed by the carrier gas, which imposes control of the temperature in all these circuits, loops and valves, so as to prevent condensation of the constituents in the effluent.
- a heating system 58 maintains a sufficient temperature of about 200° C. for example.
- the time of transit of the constituents should not exceed about 120 seconds for the system to be operational.
- a determined gaseous mixture is injected at one end of the line and the appearance of this mixture is detected with a mass spectrograph connected to the other end. The following values were obtained with a 100-m long and 10-mm diameter transport line:
- the cnditions of extraction, transport and analysis of the C1-C8 constituents are variable and depend on the nature of the drilling fluid, on the nature of the formations crossed by borehole, on the rate of circulation of the drilling fluid, on the tamperature of the fluid and of the ambient air.
- the system according to the invention therefore affords the advantage of allowing a high adjustment flexibility, whether for the P and T conditions during extraction, the flow rate and pressure conditions for the transit time or the injection of a sample into the chromatographic analyzer.
- valve 52 (FIG. 3 a , or 3 b ), i.e. at the ends of sampling loop 53 under the most unfavourable conditions, i.e. valves 56 and 57 closed.
- valve 52 can be pilot-controlled if need be.
